I was filing my taxes through turbo tax. Wanted to set up a payment plan. It took me to the IRS website. Plan set up, initial pay made now how do I finish filing?

You need to go back to TurboTax and finish filing the return:

1. Open your return
2. Select File.
3. Select Continue next to Step 3.
4. On the We've determined the easiest way to file your taxes screen, make sure e-file is the selected status. If it's not, you can select Change.
5. Continue through the screens to double-check your information before e-filing and transmitting your return.
