It would be very strange indeed if the software was just throwing a random number is that column. So I would have to assume it is coming from somewhere. When adding up withholding on Form 1040, it has lines for withholding from Form(s) W-2, withholding from Form(s) 1099 and withholding from "Other Forms". Do you have any unusual withholding on one of these "Other Forms" that maybe TT is not handling correctly?
Other things to try. Get your source documents back out (W-2s, 1099s) and verify your entry of withholdings into TT ties with no overrides. And, not to belabor this point or cast doubt on your adding skills, double check that the numbers you input add to the correct total. I had a problem a couple years ago tying out some withholding and payments I made. I bet I worked on it for over an hour. Kept adding things up and it wouldn't tie. Turns out I had one item, some number like 12,696. Yet every single time I looked at that number and entered it into excel or a calculator, I entered 12,966. It wasn't until I got all my source data back out and entered each number very slowly into the calculator that I realized what I was doing. Other than these few suggestions, I have no other help for you. Sorry. TurboTax will have to step in.
