Never received my 2020 return payment

I filed about 2 years ago and it says my refund was received and accepted by irs the same day or day after and I never got my direct deposit for my first two stim checks ..the irs website says no record of any taxes filed that year ,but in fact when I log onto this turbo tax website it shows my refund payment of 1800 was completed..... not sure why or how to know what to do next as I'm sure there's a simple procedure...thanks.my direct email is  xxxxxxxxxx@xxxxx.xxx
