Why does ProSeries "suggest" an amount in charitable cash contributions input window on Schedule A? For example if I type 50, it remembers a previous amount and inputs 500 when I hit enter even though I only typed 50. 

Suggesting words or phrases as you type is fine.  But NEVER suggesting amounts!  And I shouldn't have to type the decimal every single time since numbers are rounded anyway. 

Proseries needs to fix this error.  2020 software is the first year I've had this issue and only in the charitable cash contributions window. I have to really watch for it otherwise I find overstated charitable deductions when I review.
