Methodology:
1) Download your income transcript from the IRS using your IRS account.
2) Make sure all claimed income on the transcript is included.
3) Do the puzzle.
4) Print and file.
Be sure you have a copy, either scanned or electronic, of all documents on your computer. Ditto all tax return filled in forms. Use the fill-in pdf’s the IRS provides.
Do not miss a filing date. File a tax return missing important documentation if necessary, but file. Similarly, pay the tax you owe, or estimate you owe on time. The penalties for late filing and owed taxes are severe. You will not make a serious error if you work from the income transcript.
To add to this even if you can't pay, still file your taxes. It's so much better to only be on the hook for not paying than both not paying and not filing.
