Re Stimlus payments and Irs

I filed my taxes back in January of 2020 I filed both 2018 and 2019 together. I got a letter from the IRS staying I had to verify my identity. I have tried everything on the online tool to no avail. I couldn't get in touch over the phone even before the pandemic so I haven't been able to verify my identity therefore have not received my tax refund. Will they then keep my stimlus deposit from me because of the identity thing? They have my correct banking info. Anyone that could help would be Greatly appreciated.
