Yes. In the "Federal Review" tab when preparing your return with TurboTax, you will be asked, "Did you receive any stimulus payments?" Once you answer that question, you will have to opportunity to put in the amounts of any stimulus payments you received in rounds one and/or two.
If you say "No, you did not receive any payments" and leave the boxes blank the missing stimulus payments will be added to your tax refund as a Recovery Rebate Credit.
Here is a link with more information on the Recovery Rebate Credit.
Information on your 2020 tax return will also be used to calculate and send the third round of stimulus payments.
