"Lets get some help from last years 6251" What data do I use, last years 6251?

You are being asked to provide information from the prior year tax return.  If TurboTax did not prepare your tax return, you should be able to find IRS form 6251 amongst your prior year tax documents.

If TurboTax prepared your prior year tax return, and you are using the same TurboTax account, you can also access your prior year returns by following these steps:

• Sign in to your TurboTax account if you have not already.
• Scroll down to the bottom and select Your tax returns & documents.
• Select the year you want, then select Download/print return (PDF).
