how to file multi state taxes with out paying 49.00 extra a state with turbotax

I am 23 years old and just getting started with this IRS stuff, it's crazy confusing.

 

I reside in TX, the company I work for is in Minnesota. My Company sends me all over the US to job sights for  short term assignments,

Now I get these crazy W2 forms  from my company with not only one from Minnesota but one each from the 7 different states I worked.

Some with state taxes. 

Last year I filled with Turbo tax and filled each W2 on the same forms, not additional charge. This year Turbo tax ask me, do I want to file together or separate?  But if I file together I pay 49.00 for each additional state.  I don't understand what just happened ! 

How do I file each state seperate with Turbo Tax ? I am confused. What is the change in the process?
