Received a $600 stimulus payment in early Jan. 2021. Received another stimulus payment for $1400 in March 2021. Got one letter 1444-C. Did not get a letter notice 6475. Should I have received another stimulus payment? and if so, how do I get past the step if I did not receive a letter 6475. What do I put in the amount box if I don't know what the letter had in it. Getting an account with ID +IRS has been impossible. Cannot check anything there.
