i had this same issue and i sent my forums in by mail early April, i still havent heard anything from the IRS. Their refund status page say's still processing, remind you i submitted my documents via snail mail in APRIL
All you can do is wait while the IRS plays catch up after being closed for more than 3 months ... check the WMR tool every few days for a status update when available. https://www.irs.gov/refunds
