TaxChopper is a situation-based/interview-based tax software rather than form-based.
You enter all your "raw numbers" into the system through necessary web pages under a number of tax categories and the system will do the calculation and generate all related tax forms for your return.
You can use Interview Setup page to tell the software what tax items you have, then the matching pages will be available to you.
You just go through the pages to enter your numbers.
The picture shows an example of how you get a page available. You can also watch a youtube video on preparing a typical return.
