When it asks if you paid estimated tax -- it is not asking about having tax withheld from your paychecks. It is asking if you made quarterly estimated payments by mailing checks or money orders to the IRS every three months or by going onto the IRS payment site to make them using a credit or debit card.
If you did not do that, then skip the part about estimated payments.
Enter your W-2 exactly as it appears.
