The $2800 difference sounds like you made a mistake and said you did not get the 3rd EIP payment of $1400 per person last year. If you incorrectly put that back on your return, the IRS checked and took it off. You cannot get that stimulus payment twice.
Check your online account to see if the IRS says you received the $1400 per person already.
