Can I amend My 2020 Return to correct Filing Status Electronically - Return Accepted not Finalized

My return is still in limbo. I have not been issued a refund though it was accepted. I had to send a 8962 which its been 3 weeks they have not even processed they said 6 - 8 weeks. What happens if I amend my 2020 return to include the missing 8962 and adjust the Filing Status. I have not been issued my refund as of yet. Return was accepted 2/11/21.

 

Need some direction. Please
