Get your taxes done using TurboTax

by TIN I assume you actually mean the EIN (2 digits a dash and then 7 digits) you received for your business.  there are no tax transcripts for a sole proprietorship using an EIN. so if you need the interest paid by the bank call them or perhaps look at the last statement in December 2020 or January 2021. many banks report Y-T-D interest on them.
