As a non-resident, are capital gains, dividends and bank interests considered a Georgia source income for tax purpose?

I live overseas, and visited Georgia for about 40 days in 2018 . I received interests from Capital Once bank, and capital gains, dividends from Vanguard. 

I wonder whether I need to file a Georgia tax return as a non-resident. Are the capital gains, dividends from Vanguard and bank interests from Capital one considered Georgia source income for tax purpose?
