Why can't I claim all my charitables this year?

[78-40]

I always have; the claim has always lowered my taxes.
your head says that i get 300. without them but I don't think that will be the case.

We appreciate you choosing TurboTax,

As per our TurboTax article Tax Benefits of Charitable Donations Donations and gifts are non-refundable tax credits. This means you must claim your other credits first. If that amount is sufficient to bring your tax payable to zero, you will not be able to use your charitable donations to create or increase your tax refund. If you still have tax payable, you will be able to use all or a portion of the donation amount. You can carry forward unused donations for up to 5 years but remember that donations can be claimed only once.
