Can I put 0 or less on line 11? I keep getting an error that reads "1040/1040sr Wks" Line 11 too large", although the calculation using the tool is a negative number.

I agree. I've been using TurboTax for a VERY long time and have never had any issues. This year I ran into a number of issues that required me to manually adjust the forms they created. Very poor QA this time around.

This worked for me. delete all text from that line and it went through the check no problem.
