I have a return that is being reviewed

My return posted it was being reviewed on February the 22nd I got a letter in the mail a well after that. They asked me to send in all information that they asked for. I sent everything in by fax through H&R Block.i got another letter 14 days later stating they received my information and the information is under review also. Well 16 days has passed and I called them and spoke with someone who said all my information was correct but I have to wait until it is properly reviewed. My question is after they accept it will they send me a letter they accept it and if so will the irs to go app change the status of my return to show me when I’ll be getting the return?
