Yes, it means that you won't get your refund and it will be applied to next years estimated tax bill instead.
As long as you didn't file yet, you can change it. Go back to this section -
- Log into your account and click Take Me to My Return
- Choose Federal Taxes (or Personal if using Self Employed full version)
- Select Other Tax Situations
- Scroll down to Additional Tax Payments
- Select Apply Refund to Next Year
- Proceed through the prompts and change the answer to No (if that's what you want)
