How do I know if my injured spouse form was received?

If you sent it with your e-filing, the IRS has it.  If you mailed it, it can take 8-12 weeks to show up in the IRS system.

I know it costs more, but I generally send any correspondence to the IRS via Priority Mail - it comes with automatic tracking, so you know it arrived.

I sent it after I received info they were taking my return because my wife owes on student loans.
