Why is contribution too high because earned income was zero, Done with income portion and our pensions and SS is much higher that the 7K contribution. TT Premier?

2021 Roth IRA contribution was 7K. TT Premier says that contribution was too high because our earned income is zero. All our income is from pensions, SS and small trust distribution. Income portion of return is done and our income is much higher than 7K contribution. Have not taken any distributions.
