How do I calculate my NOL carryover to 2017?

[texpop]

Thank you for your kind response.  I did locate the carryover to 2017 in my 2016 amended return.  That amount is far less than the difference between my Harvey loss and my 2016 taxable income.  Will this carryover extend into 2018 and beyond?   It seems as though I should be entitled to the entire excess amount somewhere along the line.  There is no guidance as to how the carry over was calculated from the data on form 4684.  In Publication 536 Page 6 on How to Figure an NOL Carryover it clearly states “Your carryover is the excess of your NOL deduction over your modified taxable income for the carry back or carryforward year.”

Previously people have asked this question. It appears, though I can't tell for sure, that TT may not compute the carryforward for you except perhaps in the loss year. If you open the "Carryover Wks" line 14 a/b in the 2017 seem to be places for you to enter a number. There is no right-click data source available. The first post below says that only the professional version (ProSeries) does the calc. Again I don't know if that is correct.

To see how the calculation its supposed to be done, see page 6 of Pub 536 ("How to Figure an NOL Carryover"). It is pretty complicated.
