Rejected e-file

Can you provide more information? Your original file was accepted but your amendment was rejected?

Who do you have to answer back to by the 20th?

Well I e-filed.. I didn't fill it out right... So my job provides help with taxes.. so we amended it and he fixed my taxes and I mailed it in... And now I'm getting a message in my email from the IRS saying to answer back by the 20th basically if I don't want issues

The IRS will not email you. It is likely spam or phishing.

It might be easiest to set up an account with them. You can also use https://www.irs.gov/wheres-my-refund to look at the processing of your original return and there is also a Where's My Amended Return.
