Is there a Taxable social security benefits worksheet -lines5a and 5b this year like there was last year?

Yes, it will be included in the PDF of your tax return if you use Print Center and choose the option for all forms and worksheet so that you can view or print the worksheet after the TurboTax account fees have been paid or the federal tax return has been e-filed and accepted by the IRS.

To access your current or prior year online tax returns sign onto the TurboTax website with the userID you used to create the account - https://myturbotax.intuit.com/

When you sign onto your online account and land on the Tax Home web page, scroll down and click on Add a state. 

This will take you back to the 2019 online tax return.

Click on Tax Tools on the left side of the online program screen.  Then click on Print Center.  Then click on Print, save or preview this year's return.  Choose the option Include government and TurboTax worksheets
