" Because of a mistake I'm now having trouble filing taxes for now"

Not sure why you think the stimulus has anything to do with filing your 2022 return if that is what you are now trying to file.  There is no place on a 2022 return to enter anything about stimulus checks.

What happens when you try to prepare/file your 2022 return?   Is it being rejected when you e-file?  That has nothing to do with stimulus checks.   Did you enter the wrong AGI, or did it take a long time for you to file last year?  The IRS might not have your 2021 AGI in the system.

You received an email that we cannot see that tells you why your tax return was rejected.  

Some rejected returns can be fixed and re-filed.  Some have “un-fixable” reasons for the rejection and have to be mailed instead. What is the rejection code or rejection message? 

 If it was rejected for AGI—-be aware that many 2021 returns took so long for the IRS to process that your 2021 AGI might not be in the IRS system.   Try using zero instead.

If filing with zero is rejected then file again but select the option that you did not file last year.  The IRS does not see that question and it will allow you to e-file with no AGI question.

If that does not work and you still cannot e-file, then print, sign, and mail your tax return.
