Received revised 1099-R after filing return and receiving refund. Realized no 1040X was available. Do I somehow undo this amendment or wait until the 1040X is available?

I have the TurboTax 2020 CD version of the software. I completed and filed our return and have received our refund. We just received a revised 1099-R form from our financial advisor. So, I went ahead and amended our tax return with this new information. I noticed the software said amends area is not yet ready, but saw it offered to allow me to continue. After completing the amendment, I realized the message meant there was no 1040X tax form available in TurboTax. My question is, do I need to undo this amendment or just wait until the 1040X form becomes available?
