I am currently at self-employed page. How can I add business service into my view? I need to file tax for a partnership.

I need to file tax for a partnership

A partnership is required to complete and file a physically separate 1065-Partnership Return.  The partnership will issue each partner a K-1 which each partner will need in order to complete their personal 1040 tax return. So you can't even start your 1040 return until you have completed and filed your 1065-Partnership Return and the partnership has issued all partner's their K-1.

To complete and file a 1065 return with Turbotax, you must use TurboTax Business (different from Home & Business). TurboTax business is not available as an online product, or for MACs. It's for the Windows operating system only. You can purchase TurboTax Business at https://turbotax.intuit.com/small-business-taxes/
