When you are being asked about the 3rd stimulus payment they are asking if you received the EIP payment for $1400 per person. That is the ONLY one you are being asked about for the recovery rebate credit on your 2021 return. You are not being asked about that first one for $1200 or the 2nd one for $600. Those had to go on your 2020 tax return.
If you do not know then check your bank records from about mid-March 2021 onward for a deposit of $1400 per person, or check your online account with the IRS. Did you receive letter 6475 from the IRS? They sent you that letter if you got the 3rd EIP payment.
