"Accepted" and "approved" are 2 different things. So it's not clear how you are using the term. But in any case, I'll tell you how to check on things.
If you efiled, double-check with this tool to be sure the returns were efiled successfully and accepted:

Where the Federal and State returns both accepted?
If that confirmed it was accepted, what do you see at the IRS website below for the status of your Federal refund?
https://www.irs.gov/Refunds
NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount that includes a state refund. The amount to use is on your Federal Form 1040, Line 20a.
If the IRS tool above says it is "still being processed", see my next comment below on how to phone and reach a live IRS agent, and if necessary, the IRS Taxpayer Advocate Service.
If you efiled the state return, and the efile status check tool above confirmed that your state return was accepted, here's how to track a state refund:
