I wish to do my 2015 taxes today ...(FYI: a month later I should be 'paper organized' to be able to do my 2016 with you at a later datetaxes next)

BTW: For my 2015 taxes I previously completed a federal 4868 form and submitted it during the necessary time period to do so.

You cannot use TurboTax Online to file for 2015. TurboTax Online is only for the current tax year, which is now 2016. To file for 2015 you have to use the CD or download TurboTax software for 2015. You can purchase a download at the following link.

You might get a better price from a reputable online seller that still has TurboTax for 2015 in stock.

TurboTax does not allow returns for past years to be e-filed. You will have to print your 2015 tax return and file it by mail.

Your Form 4868 extension for 2015 has expired. It only gave you an extension to October 15, 2016. Just file your 2015 tax return as soon as you can. If you are getting a refund, there is no penalty for filing late.

You can ignore the Form 4868 when you file your 2015 tax return now, unless you made a payment with that form. If you did make a payment with the Form 4868, enter that payment in TurboTax when you do your 2015 tax return. If you did not make a payment, the Form 4868 does not affect your 2015 tax return.

Then to do 2016 you only have until Oct. 16, 2017, then efiling and the Online versions will close.  Or you can buy the Desktop program.  

After you do 2015 on your computer be sure to save your return as both the .pdf and tax data file ending in .tax2015 (go to File-Save)  then you can transfer that file from your computer into either the 2016 online version or the Desktop program.  Post back when you are ready to do 2016.
