I filed my 2020 taxes and they say accepted.. but i never recieved my refund. i thought maybe i hadnt finished them but when i logged in they say accepted. what do i do?

this was in fact 2020 taxes filed in April 2021. i never received the refund assuming i just hadnt finished them I waited until this year to file both years. 2020 says it has been accepted so now im wondering my next step.
