I recommend calling the IRS as soon as possible and ask them questions. I had an issue with my taxes last year (not my fault). After calling numerous time by June, I find out why my taxes were delayed because the IRS did not receive my W-2 from one of my employers, and it causes discrepancies for my income. I obtain the information they required for me to have from my employer and send it by the beginning of July 2018. By the end of September, I had not received my taxes. I had to get a tax advocate for the IRS to release my taxes. After that, it took two weeks to get my taxes. In the end, I waited a total of eight months for the IRS to release my taxes even after having all the information they needed. I recommend to call them regularly and if you submitted all the paperwork they ask, get a tax advocate. They will help you get your taxes as soon as possible.
