Got my tax refund! That was fast

Already showing in my bank account.

About me: USA, W2, 1099-INT, standard deduction, head of household. Used HR Block online and filed on Jan 17. Requested direct deposit to my bank account. Got an email on Jan 21 saying that IRS had accepted my filing.

Edit: people are asking me if I receive some type of child credit. No clue. All I know is that I get a $2,000 credit because my child is under 17. No daycare costs. During COVID, that credit was $3500. I think my $2,000 is NOT related to my income.
