there is a carryover worksheet - not sure it's available in the version of TT your using but you can try by typing in searchbox "carryover". you enter the nol as a positive amount on line 14a of worksheet in the 2018 column. this carries it into your return. schedule 1 line 8
publ 536 which discusses NOL's says that there is a requirement to attach a computation of the NOL
as of now, in the version i have, there is no worksheet to do the NOL computation. you may not be able to e-file because you'll need to submit the worksheet you prepared to compute it. or you can efile without it and wait to see if the IRS to request the computation.
however, I can not say what the IRS might actually do, it is possible they could disallow the NOL and bill you. you would then have to contact the IRS to find out what you can do to support the NOL deduction
