The IRS official date that they opened their e-file system was 1/27/2020, that is the date the IRS start receiving returns.  Even though your return was accepted, that means the IRS has your return to start processing it.

The IRS states that nine out of 10 e-filed tax returns with direct deposit will be processed within 21 days of IRS e-file acceptance. Mailed paper returns: If you filed a paper return, please allow 4 weeks before checking the status. Refund processing time is 6 to 8 weeks from the date the IRS receives your tax return.
