You did not supply enough information, on what kind of U.S. income you have, for me to let you know which program you should use. See the TurboTax Online Product Guide . 

Your Canadian CPP and OAD benefits are treated as if your received U.S. Social Security Benefits (form SSA-1099). Form SSA-1099 may be entered in the TurboTax Federal Free Edition.

Under income tax treaties with Canada and Germany, social security benefits paid by those countries to U.S. residents are treated for U.S. income tax purposes as if they were paid under the social security legislation of the United States.

Per IRS Publication 915:

In other words, if you're a U.S. resident, you'd enter your Canadian CPP and OAS benefits as though you had received a Form SSA-1099 from the Social Security Administration:

1. In TurboTax, open your return and search for SSA-1099 (upper- or lower-case, with or without the dash).
   • Click the Jump to SSA-1099 link in the search results.
2. Select Yes, let's work on Social Security benefits and click Continue.
   • If you land on the SSA-1099 screen instead, skip to Step 4.
3. Check the first box (Form SSA-1099).
4. Enter the total Canadian CPP and OAS payments you received during 2015 in Box 5.
   • If you already have something in Box 5 from a previously-entered SSA-1099, simply add your CPP/OAS benefits to the amount already there.
   • (Uncommon) If taxes were withheld from your payments, enter the total withheld during 2016 in Box 6.
5. Click Continue and follow any additional instructions.

The U.S.-Canada tax treaty also applies to the Quebec Pension Plan (RRQ). Please note that the agreement only addresses government-issued social security benefits, not money received from private Canadian pensions.
