S Corp -- PPP loan Forgiveness and Tax extension Deadline -- Sept 15 2021

I am using TT Business Desktop for S corp. Took  loan on PPP on May 14 2020 but the Lender has not yet opened the forgiveness application for round I on his Portal .  

My question is :

 

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?

 

2) How do I handle the PPP loan amount in my TT Desktop product either ways?

 

Thanks

Kevin
