Taxes in multiple states as non-resident

1. Where is the list of state taxes that support non-resident filing?  I've looked for 20 minutes; found it for TT Business but not Personal.  

2. I'm wondering if it can handle my situation anyway because it's kind of confusing for me to wrap my head around. 

I pay taxes in multiple states.  Usually I do the non-resident states first, which is from partnership income on a K1.  The states look for a ratio of income earned from that state compared to my total income.  Then I do my home state taxes and get partial credit for taxes I paid to those other states.

 

But this year my 1040 reduces my partnership income a lot due to tax loss carryforwards (from the prior year K1).  I'm not sure how to break the tax loss carryforwards across the different states.  But if I don't, it looks like I had more income in each state than I really had in total.  Would the TT state programs ask me to allocate the losses across the states in which they originated?
