Turbo tax stated my federal return was accepted on 5/23/2020. I have yet to receive my return! It has been months. I think Turbo Tax did something wrong.

No you should not redo your taxes.  Once your return is accepted, only the IRS would know when you will receive your refund.  TurboTax does not get any updates regarding the processing of your return or when you will receive your refund.

You can checked the IRS website Where's My Refund for your Federal information?

 If you mailed in your return Federal return, during Covid-19 the IRS was closed & they were not processing mailed in returns.  They have recently started processing mailed in returns & they are very backed up.  It can take awhile for your return to show in their system.  

You can also contact the IRS.  The IRS telephone number is 1-800-829-1040, and they are available from 7 a.m. – 7 p.m. Monday thru Friday. The best time to call is early in the morning.
