Hello, I've tried calling the IRS for weeks now and their online help form is down, of course. Hoping someone can help me.

I filed my return under the wrong status (married "jointly") instead of "separately". I sent in my amended return 1040x last week. I see that the IRS is saying up to 16 weeks processing time this year. Well, b/c I did this error, my husband went to file his own tax return (also "separately") but the system rejected his return saying that ss# was already submitted and that he would have to mail in a paper return.

Here is my Question: Can he just mail in his regular 1040 return or will he also need to now file an amended return 1040X?

What a nightmare of a mistake Thanks for the help!
