Hello!
You've been given lots of good advice so far, I wanted to give it to you from the perspective of someone who did exactly what you did a year ago, and it led to accidentally killing my first fish. The problem is that the internet is full of random and outdated information, and a lot of it sounds logical so we follow it, often following it even obsessively and testing things, thinking we're working hard and doing well, when actually because we read and followed the wrong information it is not helping, and could be dangerous to the future inhabitants of your tank.
Basically, you don't need to worry about anything you're worrying about now. Don't worry about cycling, in fact stop thinking about cycling or the process of it completely, it's not a particularly useful concept for understanding what's happening in your tank. All you need to do is to get your plants growing and thriving over the next 6 weeks. Focus on looking after the plants, and the plants and bacteria will grow a big enough community to support your first animal additions. Cycling works differently in a planted tank, because plants do so much filtering, and they provide an enormous surface area both in the water and in the soil for more bacteria to flourish, so not all the business is happening in the filter. Ammonia cycling is used when there are no plants, a way to brute force a community of hard bacteria, but planted tanks are much more chill and pleasant than that, they just need time and a bit of tlc to thrive. Relax, this is what planted tanks are for, it is a more holistic way of doing things and it will reward you over time.
During these 6 weeks, you should do 50% waterchanges weekly. This is to keep the water as clean as possible, so that the plants grow well and to discourage algae from settling in (which loves ammonia). This will also help reduce the amount of ammonia you added (which did not help, but don't beat yourself up about it cos you didn't know), by the time the 6 weeks is up you want to have pristine water, and adding contaminants like ammonia goes against that. Along with water changes, you should add fertiliser to help your plants grow (for people new to planted tanks, TNC Complete is a great all-in-one). If you have any problems with growing your plants, or want any advice don't hesitate to ask! Some plants do well, and others don't, so over this 6 weeks you might be moving, replacing and adding new plants too.
A planted tank is an eco system, and your building blocks are the microbiome and plants. Look after the plants and they and the microbiome will thrive, and your fish will thrive in turn. No ammonia needed 🙂
