On my tax return what form do I use for temporary assignment housing in adjacent state?

My wife and I are Nevada residents.  After the pandemic, she was asked to become a traveling nurse to help in California due to a shortage of nurses.  She was only needed 3-4 days a week, so we rented an apartment in California near her work and traveled back and forth as needed.  Where on my tax return would I enter this temporary assignment housing cost?  Which form, please.

Thank you,
