State tax filing

My husband and I were part year residents for MD Jan. 1, 2021 to August 24, 2021 and then moved to NC from Aug. 25th - Dec. 31st.  His company stayed the same and is located in Rockville, MD. Only MD taxes were taken out for all of 2021. I believe I correctly got credit on MD but I cannot figure out how to fill out the NC part year form. I am hung up on the question where it places his whole wage in and has it marked as Not NC source income. I thought since I calculated MD's amount as 65% and NC amount as 35% on the MD return, that Turbotax would place everything appropriately. It says if I need to make changes in this screen, then I have to do it at the W2 area in the Federal return. I am scared to change something there since that is not the W2 that the IRS sees. I'm not sure if I missed checkmarking something that it didn't allocate it for me. Also if I am on the right path and I need to manually alter it, do I need to send paper returns to the states  - meaning I send MD a copy of my NC return and vice versa - therefore losing out on the quickness of e-file. If someone is able to help with an example calculation or how I should fill out the questions. Thanks in advance.
