what does word "Income" mean on Tax renewal form - does it mean income from self employment or income from benefits?

Do you mean the tax credits form?
It has different boxes for different types of income.

yes tax credits, it jut says Income

which box number and I'll check my software

Step 3 - is your total income for 2020-2021 likley to be less thn 16385?

It would include taxable benefits like most state pensions (for instance I receive pre-Apr 2017 Widowed Parents Allowance which is taxable) but not non-taxable benefits, e.g. tax credits, housing benefit, universal credit, child benefit.
You'd have to check the specific benefits you are referring to.

It's the same figures you'll have added up to get to your 2012-20 tax credits income.

It's taxable income, so employment earnings plus some (but not all) types of benefits. Are you willing to say which benefits you receive?

2019-20 figure (no idea where 12-20 came from!)
