Retirement tax questions

Yes, I kept getting the same error.  It would not let me E file.  Told me I would have to print out the form and mail it as if I did something wrong.   After a couple of hours asking the ? questions.  I finally got the solution.  Yes it did have a - (Negative number) on that line.   Line 11 on form 1040 showed a zero and said it was too large.  Everything I did would not fix it until I took out the zero and left the line blank.  Then it worked perfectly.  I was then able to e file.   I've used Turbocad for the last 7 years and never had a problem.  Now using the online program it failed.  Probably due to a software programing issue.  I would like Turbocad to respond to this message and tell it's users that they failed to provide good programing and failed to even notify it's customers of this problem.  I'd like a refund.
