Clarification on definition of “annual earnings” for tax relief on private pension contribution

According to gov.uk, “You can get tax relief on private pension contributions worth up to 100% of your annual earnings.” If I make one-off contribution to Self-Invested Personal Pension (“SIPP”) which is a Defined Benefit Scheme, please clarify if “annual earning” including 1)dividend income, 2)savings income and 3)residential rental income. What is the maximum amount of one-off SIPP contribution I can made, assuming that I have £1,000 salary income , £20000 rental income, £15000 dividend income and £20000 interest income?
