Resolved!! California resident filing non-resident state tax return in North Carolina

Hi, I have several questions about saving money while filing multiple state tax returns, so thank you in advance for reading and responding! 

~  I live and work at a full-time onsite job in California, and file federal and California state income taxes every year through TurboTax Deluxe with state disc desktop version (because I also help file for my uncle an cousin who don't make much money). 

~ In 2019, I did online freelance work (all REMOTELY) for a company based in North Carolina and got $8,000 in 1099-MISC income. So do I have to file North Carolina state individual income taxes since North Carolina requires nonresident to file  a state return (https://www.ncdor.gov/taxes-forms/individual-income-tax/nonresidents-and-part-year-residents) if their federal gross income exceeds $10K?

~ If I do, I assume I can get credit on my usual California state taxes by filing a Schedule S -- Other State Tax Credit Form (https://www.ftb.ca.gov/forms/2019/2019-540-s.pdf)  

~ I am using TurboTax Deluxe State disc desktop version, which includes a free download for one state (I chose California). I usually pay a fee of $24.99 to e-file my state tax returns for Calif.

 

My questions are: 

1. If I download an additional state forms (for North Carolina) TurboTax charges an extra $45 fee) plus the $25 e-filing to file the return. Instead, to save money, can I file directly via the North Carolina state tax website? (I might have to use the free Credit Karma software site).

2. If I do file North Carolina separately, outside of TurboTax, how do I to input that amount while doing my California taxes via TurboTax? Which forms do I need to use/record the amount on? Will TT require me attach the North Carolina state return -- and how would I do that?    

Thanks in advance for answering these questions! 

Sincerely,
