After you file

If the rest of your question was that the account is no longer valid then the bank would have rejected the deposit and the IRS will automatically convert it to a check mailed to the address on the return ... this process  usually takes about 3 weeks however the IRS has been mostly shut down so this may take longer ... on 5/4 the IRS is putting many of their staff back to work so hopefully things will get back to some sort of normal soon.
