Depends on if you took child tax credits if you did IRS site saids to start looking for those returns around 23rd other wise as long as there no errors with your return should be 21 days also know returns are pulled randomly to approve them not by date filed. As to state many states have posted it could take weeks to get returns they are checking returns for fraudulent filings i.ve send and where from 14 days to 12 weeks .Just check my wmr once daily as it only updates once if after 21 days reach out to IRS.
