You are only being asked about the 3rd EIP payment--- the one that was issued in 2021 for $1400 per person. You are not being asked if you received the first or second one. If you received the $1400 you must enter that you received it.
You do not say why you did not get the first or second stimulus checks---if you were someone else's dependent at the time in 2020 then you were not eligible to receive those payments, or if your income was too high in 2020 you would not have received them. If there was some sort of mix up and you should have received them then you can still file a 2020 return or an amended 2020 return to seek the first or second stimulus payments as a recovery rebate credit for 2020.
