You also asked how long it takes to get your refund. It depends on how you filed.
The IRS says 9 out of 10 filers who efile and choose direct deposit will get their Federal refunds within 21 days after being accepted. Some returns are processed fairly quickly, while others require additional processing due to specific items in the return. Some are pulled at random for more thorough investigation.
If you filed a paper return by mail, even in "normal times" it can take about 6 weeks to get a Federal refund. But with the Coronavirus emergency, however, paper returns are currently not being processed for the time being, so a delay will be common once they start processing the backlog.
