How can I/Is it legal to remove the Retirement Savings Contribution Credit?

Basically, I qualify for an $11 Retirement Savings Contribution Credit, but that requires filing a Form 1040, which TurboTax Free Edition doesn't cover. The cost to upgrade is ~$50. I'd rather save myself $39 dollars and just not claim this credit, but I can't figure out how to remove it. It may be possible to simply remove my 401(k) contributions from my W-2, but I have no idea how legal that is.

Greatly appreciate help,

Coney
