For 2020 I received three W2's. I accidentally only filed 1. My return was accepted on 2/10/21. I have not received my refund. Can I file an amended return now for 2020?

I e-filed one W2 for the 2020 tax year. That one W2 was accepted on February 10th, 2021. It still is processing on the IRS site over a month later. Since it was accepted, can I go ahead and file the amended return for the other two W2s I missed? And if so, can this be done electronically? Thank you!

Slow down. 

You cannot amend a tax return that was just accepted.   You have to wait for it to be processed by the IRS.  Trying to send in an amended return while they are still processing the original return could confuse things and delay your refund for months.

Do not try to change anything on your return now.  When you amend, your Form 1040X has to be prepared from the return exactly the way it looked when you filed it originally.   You have to wait.   Once your return has been processed you will complete a Form 1040X   --- which is not yet available --- and submit it to amend the mistakes made when you filed your original return. It takes the IRS at least four months to process an amended return.

The Form 1040X you need is under revision and is not ready yet.  The Form 1040X does not become available in the software until the end of March 2021 (subject to change).
