I am stuck on Non-Maryland losses and adjustments

[korsibor]

I am filing jointly and currently working on my Maryland state taxes. I worked in 3 states - MN, MD, and PA. 

The picture below shows two queries - I answered the first by adding box 1 for MN and PA W2s. Is this correct? 

Box 2 asking about adjustments and losses is where I am stuck. How do I calculate this? 

Please help. How do I calculate losses and adjustments. Is there anywhere on my W2 that I can find this information. Do I look at my 1099-R?

Non-Maryland Losses and Adjustments would be things like capital losses or losses from rental properties.

so I guess I can enter zero. I do not have any rentals or major capitals, the only thing that I can think of is probably losses from investments such as stocks, which I don’t remember making any sales last year.

You can leave it blank - don't enter a zero.   Did you live in multiple states or just work in multiple states? 

Do I have to file tax returns in more than one state?

Why would I have to file a nonresident state return?

If you were a resident of two different states during the tax year, follow these steps.
