Military vs ITIN vs Stimulus

I’m Active Duty Military. My spouse is a US citizen by naturalization with a SSN dating back 5 years. We electronically file our taxes jointly each year using TuboTax and receive our return via direct deposit. Each year, I manually update her SSN on the 1040, but our 1040 always reflects her old ITIN instead of her SSN once filed. We qualify for the stimulus, but I believe we have not received payment because of her ITIN reflecting on the 1040.

 

How can we recoup our stimulus payment?
