Yes, you should enter exactly what you received. Be prepared for proof of deposits to match the amount you actually received. Also, there could be a delay, however you should receive all you are entitled to. This is reconciled on the 2021 tax return using the Recover Rebate Credit (RRC) under the Federal Review tab.
You are not required to enter more than you received. Double check the IRS website to see if they changed the amount there, also make sure they didn't withhold any funds or any reason.
