I tried doing my taxes this weekend using H&R Block (I always TurboTax in previous years). I decided to use H&R Block for the 10% Amazon refund bonus. It's not worth the headache. The only EV tax credit that H&R Block seems to support is the $7500 federal tax credit (30%). It does not support the EV charger installation federal credit or the Colorado state EV credit ($6000). It's been such a hassle. I'd recommend to everyone that hasn't done their taxes yet, to avoid H&R Block.
