Hi Tammy,
Guess who!
Well I did read your other post about what happened with your tax return.
You can tell them you didn't file, if you want to - but as you said you don't really want to lie (and my personal opinion is that you shouldn't).
You can submit a correction to your return using this form
1040X The instructions for the 1040X are
hereI've never corrected a return but from what I read on the form for the correction you just make the change at the top that you need to (
Married filing separately - unless you are really filing jointly?) and then explain it at the bottom of the page, be sure to put your Husband's name in the explanation of what you are changing as when you file Married filing separately they ask for it on the 1040.
If you did this then you could honestly say you filed Married filing separately and the transcript would reflect this after they made the update.
As for your other question - #25 on the DS-230 you mentioned, is Previous visits to the United States so I assume you meant 25 on the I-864.
There isn't really an option that your situation falls under to mark off here, as you mentioned. If it were me I would mark yes and put an * beside it and then I would put a note at the bottom of that area (under where it says Optional): *I was not required to file for 04/05/06 please see attached.
Then you can write up your letter saying you filed for 06 even though you were not required to and that you did not file for 04 and 05 because of - whatever you were going to tell them.
Anyway that's my take on it.
