If the amount of the credit is less than the upcharge, you can remove the credit by indicating that you are a full time student in your personal information page. This should not change anything else on your tax return. (Students are not eligible for the credit.)
If your total income is less than $36,000, you can use the IRS Freefile version of Turbotax without being charged an up-charge for this situation. However, since FreeFile is a separate program, you will have to make a new account and start over from scratch.

You might also be able to install Turbotax on your own computer. The "desktop" version of Turbotax Deluxe costs less than $50, if bought from a discount retailer like Amazon or Costco, plus it will charge you an extra $25 to e-file your state tax return. (You can print and mail your state return for free.). The fee for the Desktop version might be less than what Turbotax Online wants to charge you. Be sure to buy the version marked "Federal plus one free State."
