e-filing for 2019 returns didn't officially start until 1/27/2020. professionals will tell you to wait several days after opening day, there are always glitches and the DIY big box companies have thousands of returns sitting in queue to send in opening day....no professional wants their client returns caught up in that mess. So the IRS got it but it's likely it was never successfully processed. you can check by registering at the IRS website to see if there is a transcript of your return. if it doesn't exist, it was never processed.

if it was, then call because you should have gotten your refund by now
