Turbotax showing excess HSA contributions on carryover worksheet from 2017

I'm working on my taxes on Turbotax Premier (CD version). I noticed line 11a of the Carryover Wks claims I have $4,819 in excess HSA contributions carried over from 2017 that it's making me pay tax on (schedule 4 line 59). However, I did not have any excess contributions and the $4,819 amount is what was shown on my 2017 W-2 as employer contribution. and was not disallowed. And Turbotax 2017 does not show anything on that corresponding line (which presumably it would if there were in fact an excess contribution). BTW I did not have an HSA in 2018.

Obviously I can zero out the amount on the carryover worksheet but would like to understand why this is happening and perhaps get it fixed.
