How can I apply our refunds to estimated taxes for 2018?

[MollsBBU]

To reach that section of TurboTax, please do the following:

1. From within your return, click Federal Taxes 
   Or, Personal if using Home & Business
2. Then, in the white bar at the top, click Other Tax Situations
3. Then, under Additional Tax Payments, click Start next to Apply Refund to Next Year
4. You'll see two options on the next screen:
   -Apply all or part of it toward next year’s tax bill, or
   -Give me my entire refund now

Since you select a dollar amount, rather than a percentage, it is best to address this entry when you are done going over income and deductions so you have the accurate refund amount to enter (for 100% of it to be applied).
