Doing 1040x -- change amount to be applied to 2021, or send a check?
In November got a revised 1099, which increases my 2020 taxes by $50.
I had used Turbotax Download/CD/Desktop to mail my original return. In that original, I had a $2000 overpayment, so I had $1990 applied to my 2021 taxes, and had $10 credited back to my checking so that I would know the return was processed.
To make the amended return I made a copy of the *.tax2020 file, opened that copy, and successfully got into the amend process. Where I got confused is that I started changing the amount to be applied to 2021 (line 36). This seemed to confuse things. I am thinking of starting over, keep $1990 to be applied to my 2021 taxes, and mail a $50 check with the 1040X to keep things simpler.
Are there suggestions or comments on the better way to do this? Thanks.
