Motor vehicle deductions in D5 causing validation error

We are having the same problem and we thought you had to delete it, but it seems if you go in and out of the schedule a few times it seems to go away.    Very frustrating as no logic to making the error go away.3

This needs to be fixed along with several other errors in 2020 tax.  In nearly 20 years of using this, this seems to be the most error prone release of tax I have ever encountered.
