Its mostly personal preference as to whether you prefer the increased functionality of the desktop program (such as Forms Mode) or if you prefer the convenience of the online (i.e being able to work on your return anywhere and having TurboTax store your files). If you liked working with the desktop Business program, then you will probably like working with the desktop personal program.
Both versions can easily handle a K-1 entry. But, with the desktop program, you can actually enter a K-1 in the Deluxe program; whereas, you will need TurboTax Premier with the online program. So, you would probably save money by going with the desktop Deluxe program. (Of course, if you have other investment income or another business, you might want to upgrade to a higher version in the desktop if you feel you need extra guidance. But, the forms themselves are all available in Deluxe.)
If you decide to switch to the desktop for your personal taxes, let me know and I can give you further instructions on how to transfer your 2015 online file so you can jumpstart your 2016 return in the desktop program.
