1) If the lender does not open the forgiveness application before Sept 15 or if the loan if not forgiven by Sept 15th,2021, Do I need to file the 2020 taxes before Extension deadline of sept 15, 2021 and get back and do an amendment if the loan if completely or partially forgiven after Sept 15, 2021?
Since it is a LOAN and not income it is immaterial when it gets forgiven ... just file the return on time.
2) How do I handle the PPP loan amount in my TT Desktop product either ways?
Again it is not income or an expense so the only place you may need to mention it on the return is on the balance sheet so your books and return match.
