State tax filing

this line is blank back to 2017 tax year just checked all done on TT so weird I don't submit until all errors go away and dont' recall this ever coming up until trying to finish my 2019 tax year taxes.  Should I just track down my vehicle reg fee and enter for 2019 tax year returns since 2017, 2018 were both blank or?  Thank you in advance to whomever can help me - this is the only thing holding me up to submit my tax return.
