Depends. The 570 code stops your return processing and 571 code releases your return for processing. The 570 code indicates additional liability is pending. It looks it will be released on 4/12. Normally the IRS will add an additional week to investigate dependents. Did you have earned income tax credit and/or additional child tax credit? If you have earned income credit and/or additional child tax credit, it is probably delayed. Returns with either of these credits are covered under the PATH act, which gives the IRS authority to delay the refund to verify dependent information on your return.
It could be a number of items that stopped the processing. Unemployment benefits, dependency questions, recovery rebate credit/stimulus payments mismatch, just to name a few. But at least your have dates indicating your return will start processing. You may not receive the total amount of the refund you requested. Watch your mailbox for a letter of explanation from the IRS.
