The purchase of goodwill is a capital asset and is subject to amortization. The goodwill is not a line item pre se on Sch C, F, or E. But it becomes a line item on an amortization schedule. The amount of allowable amortization ends up as a deduction on whichever business schedule you are filing. Similarly as other depreciable assets.

I'm not familiar with TT itself, but I think when start; say a Sch C, there is a question about whether you started the business this year or are continuing a business.
