According to the general press and the relevant IRS pages, if you e-filed your taxes for 2018 (or even 2019), and you used direct deposit, the stimulus checks will be deposited automatically into the known account.
What could be the reason that to fail? I used the IRS website today to find out when to expect my stimulus check, and it claimed they 'are missing the information to deposit it' automatically.
Now it could be that the IRS is really missing my deposit data, but I have been using the same account for the last ten years, filed my taxes for 2019 on Mar/11, and the IRS deducted today (that is, Apr/15), my tax payment for 2019. They were perfectly able to deduct it, it's gone from my account, but they 'don't have my account information'?
I never had a high opinion on the quality of their processes, but that is incomprehensible even for me. How can they use the account information and at the same time not have it?
