I am in the process of amending a 2020 tax return filed on February 18, 2021.  The 1040 had charitable contributions of $430, $300 allowed.  On the state return the original return had $130 ($430-300) and 5% allowed as the deduction.  The return was efiled.  As I am amending it I see in my Pro Series that the original filed state return has been changed to $430 from the original amount of $130.  Why would Pro Series change a return that was filed and accepted as is by the IRS?  If Pro Series made a change in the calculation, or by some chance the state changed, why wouldn't the original return stay as filed?  This is not acceptable.  Has anyone else encountered this?  I am guessing it changed during an update.
