I recieved a letter from the IRS saying that my ex husband and I owe $7806.25 from 2017 taxes. We forgot to file two W2s from that year but we have them now - could we just file them with this years t

It's a notice CP22A and it says "Changes to your 2017 form 1040A." I spoke to someone at the IRS who told me about the 2 W2s but was unable to offer any other advice.
