You can manually input form 172 and attach as a pdf.  Easy to do.  In Proseries open up forms menu, type in NOL (select NOL Worksheet).  It is a line for line copy of form 172.  Just use a fillable pdf of IRS Form 172 and enter the numbers from the NOL worksheet.  And of course enter in the clients info at the top of form 172.  Attach that pdf to the tax return and bypass error check when converting and sending.  Business as usual.  Or wait for the update. 🙄  Which may be kicked down the road come March 6th.
