Since you mailed your return in a few weeks ago, there is a chance that the mailed return may be rejected as a duplicate submission and you will need to resubmit the initial return again as an amendment.  That's because computers, not humans, process the majority of those forms - even the ones mailed in and it won't understand what has taken place. 

Just keep a copy of those handy in case that happens, and feel free to call us if you get that notice so that we can help you to prepare the amended return necessary to get the "fancy forms" properly documented with the Form 1040X.

It doesn't make you dumb - these things happen - and we will be glad to assist you further when the time comes.  I'm sorry that you're wife is currently out of work - I hope things turn around for you soon.  Stay safe!
