Thanks, to clarify any confusion: the problem is that the 2019 Turbotax premier online does NOT provide an interview for bad debt so it never gets the right information it needs to print out or to efile to IRS.
The question now is, given that there seems to be no way to tell Turbotax 2019 premier online all the information IRS requires for a nonbusiness bad debt deduction (short term capital gains loss), can I efile it and then separately mail the information required to IRS, based on this Turbotax help topic on Form 8949 (nonbusiness bad debts are listed on Form 8949 and Schedule D, although this Turbotax help topic does not mention bad debt):
If you're required to mail in forms 8949 and 8453, do so within 3 days after the IRS has accepted your e-file. Here's the mailing address:
Internal Revenue Service Attn: Shipping and Receiving, 0254 Receipt and Control Branch Austin, TX 73344
(That zip code is actually a zip plus four that ends in -0254.)
