Hello, I have filed my federal return and it was accepted on 4/17, but now that it is 6/1, I still haven't received my refund. Is this normal time frame? Thank you

That is normal this year.  The IRS remains seriously backlogged due to all the new tax laws and extra stimulus filings, as well as unprocessed 2019 returns still left over from the COVID shutdown.  Lots of other folks are still waiting (some since mid-February), so please continue to be patient.  Also see:

Thank you so much for your reply.

I greatly appreciate it and it was very helpful.

Have a great day
