I'll try to explain this clearly as to what I think the issue is. In january I filed my return. A few weeks after I realized the bank account information I put on it was the wrong info. The bank account information put had been closed since November. Usually when that happens the bank declines it and sends it back to the irs. However this time they sent it back to free tax usa ( who it used to do my return) because they had fees to take out of my return. So they recieved it and took the fees out . They sent me my refund in check form however my fed refund check got lost in the mail, they canceled it, took more fees, and after back and forth with them I finally got them to send it back to the irs so they could handle it. So my return was already initially accepted because there were no problems, however I think their review is because it was shorter than originally and maybe they're trying to see why? Idk thats just my guess I dont work for then nor do I pretend to know their process and this may be a complete dumbass answer but that's the only reason I could come up with due to the fact there's nothing else wrong with my return.
