I'm using TurboTax Self Employed, but I want to use TurboTax Premier instead. Is there a way to transfer my existing entered tax return info to that package?

Unfortunately no there isn't you have to clear and start over to downgrade:

You can now downgrade with the Clear and Start Over feature but bear in mind that the different TurboTax "flavors" handle different tax situations and their associated forms.

For example, if you want to downgrade from Deluxe to Federal Free Edition and you're itemizing (Schedule A), you can clear and start over with the free edition, but once you enter your itemized deductions in the free edition, you'll be asked to upgrade to Deluxe.

Here is a short list of some common tax situations and the online products that now uniquely support them:

·       Itemized Deductions (Schedule A/1040)- Deluxe, Premier, and Home & Business

·       Capital Gains or Losses (Schedule D) - Premier and Home & Business

·       Rental Income (Schedule E) - Premier and Home & Business

·       Net Profit from Business (Schedule C-EZ)  - Deluxe, Premier, and Home & Business

·       Profit or Loss from Business (Schedule C) - Home & Business

If you are looking at TurboTax Federal Free Edition, keep in mind that this version is intended for taxpayers with very simple returns (Form 1040EZ filers with the standard deduction), for example first-time filers and students.
