You can search for stimulus and use the Jump to stimulus link to be taken to that section in TurboTax. If you search and you don't get the link, that means either your AGI is too high to qualify for the credit or you are filing as a dependent. If your AGI is too high, TurboTax will not ask about the stimulus as you can't claim any credit.
Read the screens carefully in that section to ensure the processing of your return is not delayed.
