I completed the 1040A, ran the review, and was told the return was correct. But obviously not. Several other people have the same complaint. This program error needs to be fixed.
It's clearly the line number showing up in the amount field, but I have confirmed that it only shows up there on the PDF copy. I noticed that all of the line numbers seem to appear a second time at the end of each line of text, but only 49, 50 & 51 show up in the amount field.
I have reported the bug to TurboTax. Thanks for confirming, and I'll let you know if I hear something.
