Turbo Tax Deluxe and Turbo Tax Business

I have always used Turbo Tax Deluxe for my personal tax returns but this year I loaded up Turbo Tax Business due to a loss in the family requiring an Estate. I don't see that I can create a personal tax return (not a business) in Turbo Tax Business.  Can I reload Turbo Tax Deluxe without losing Turbo Tax Business, as I am still working on the Estate.  I have a Windows operating system - Desk top computer.
