I used turbotax online last year, using application on computer this year. Need to recalculate last year's return

[mesquitebean]

Please explain what all you are doing.

What do you mean by "recalculate last year's return?"    Are you referring to a 2017 return, and if so, was the 2017 return never filed, or are you saying you need to prepare a formal amended return Form 1040X to correct a 2017 return that you filed last year?

What year software do you have on your computer?  2017 or 2018?   Have you downloaded the *.tax2017 data file from your online account?

I see you have another thread on this issue.  Having multiple threads creates confusion and redundancy, so I'll close this thread.   I can't help you with AMT, so please keep watching your other thread.
