After you file

<<But it still doesn't explain why the software came back to me during processing and stated I had another credit due and applied it automatically to line 30>>

 

because the software was dependent on the amount YOU told it you had already received....... 

 

Line 30 is simply $1400 times the number of people listed on your tax return LESS what you had already received.   THe result, but not less than zero, appears on Line 30. 

 

The IRS knows what you received (since they are the ones that sent it to you).  If you entered a number representing what you received and it did not match the IRS records, then the IRS adjusted by the difference. 

 

the issues on this board - and its every single one on this topic - reflect the user not entering a number that matched the IRS records.  TT wouldn't know what you received; it was dependent on the user entering the accurate number.
