After you file

So I just sent me admend form in. I called and they still had not sent me a letter , they told me I was under review, but they had 45 days to look at it since I know what’s wrong I just sent it in just in case they don’t fix , they I would have to wait another 45 days for whatever letter they will send out . She told me they could fix it themselves or they might need me to fix . Instead of playing the waiting game I just sent the form . I expidited , so I will call on Tuesday to see what they say
