Because you are preparing a trust return from TurboTax Business (which doesn't accept attachments), the program will generate Form 8453. You can still e-file your return, but you'll need to mail a paper copy of your 1099-B to the IRS along with Form 8453, which you can print using these instructions: How do I get a PDF of my return?
Mail these completed forms to the IRS at the address below by the tax-filing deadline:
Internal Revenue Service
Attn: Shipping and Receiving, 0254
Receipt and Control Branch
Austin, TX 73344-0254
