Good day, I started filling out a declaration for partnership. As a result, I am being told to pay 490 dollars. Although I would like to pay 160. I want pay 160 $

Did you get into the Online Assisted Business version?  You probably want the Desktop program.

For a business or Trust/Estate return you need the Turbo Tax Business Desktop program for Windows.  It is not available to do online or on a Mac.  And it will not do your personal 1040 return.  It is not the same as the Desktop Home & Business program.  You can have both Turbo Tax Business and a personal version (like Home & Business) installed at the same time.

You can buy the Window's Business Desktop program here…..

Can you clarify what product you are using - are you using TurboTax Business to prepare a Form 1065?   Or are you trying to file a personal tax return?
