1040 ES 2020

I filed on 3/15/2020.  Electronic return was accepted.  I had a large over payment.  I applied part to 1040 ES for 1Q installment and the balance was refunded.  Now that payment due date is deferred, how can I get back the money applied to 2020 so I can pay it at the latest date for filing 1Q 1040 ES?
