TurboTax is autofilling last year's refund incorrectly

[ssf-gm]

TurboTax is autofilling last year's refund incorrectly. Is this a common problem? I would have assumed that since they calculated the amount last year that it would be exactly the same - nothing for them to import or re-calculate, simply pull from their database. Am I potentially missing something?

This can happen if you made any changes to the return after you filed  (last year the late tax law changes automatically changes some returns).  If the amount is incorrect simply enter the correct amount and continue.

I did not make any changes to my return after filing. The number on my last year's tax return (which I downloaded from TurboTax after filing) is different from what they autofilled. Weird...

Anyway, I will just enter it manually then
