Deductions & credits

I have no idea what the problem is, but I have a similar one.  For line 42, the program incorrectly calculated the "multiply line 40 by line 41", giving a result that was more than 20 times the correct answer. After talking with a techie on the phone, I learned about the "overide" procedure - which fixed the problem BUT now the program flags an error for line 42 (even though it is now correct!),  As a result, I supposedly can not file electronically because the error would be flagged - so it's back to snail-mailing my return for the first time in many years.  I am NOT impressed - similar problems have been reported for over a month.  I can only imagine the nightmare of trying to fix this bug ...
