K1 is considered passive income and not earned income and that may disqualify you from the credit.
According to IRS rules, you – and your spouse if you file jointly – must have earned income from wages, salaries, tips, other taxable employee compensation or net earnings from self-employment. One spouse may be considered as having earned income if they were a full-time student or were physically or mentally unable to care for themselves.
