I have unused donations from previous years. How can I claim them in the current tax year?

If you have chosen to autofill your return or to Roll-forward previous year's return, the unused donations will be automatically included in the tax return. If you have not roll-forward you return, go to 'Form Manager' and search for the 'Donations' form and on the first page, in the section 'Donations made before 2022', enter the amount in the year and type of donation that is applicable.
