Turbo Tax Online-Installment Sales Principal "Fill-in Box" not flowing to other forms correctly.

2020 Business Income-installment sales principal "fill-in box", does not

  • -generate a 6252,
  • - or a 4797,
  • -Schedule D,
  • - Line 7,1040,
  • -populate Income Revisit/Edit page
  • -or carry to Capital Gain on my state tax return

I have discovered a 6252 was not generated with my 2019 tax return, but all forms were generated correctly for 2015-2018 from the date of the installment sale.
