During 2019, moved from NC to SC where my fiancé lived and then got married. How to file state taxes?

In the middle of 2019, I moved from NC to SC, where my fiancé lived and worked. Before the end of the year, we bought a house and got married. I continued working for the same company the whole time. So now, I'm working on our taxes and am starting to regret not paying someone to do it for us. :( It's prompting to do a South Carolina Nonresident Schedule for half the year for both of us, even though she lived here all year. How should we file? How do I fill in the Taxable interest income, dividend income and Capital gain fields? Do we do the SC-1040 or the Schedule NR? Anything else I should be aware of? Thanks!
