I used to be a pretty happy TurboTax user due to all the automatic handlers/connectors.

This year I leaned fully into LLMs and had Claude build everything from scratch then used the Gemini & Chatgpt to check. While it took time to get all the marking just right, it was, relatively speaking, pretty easy since I downloaded the previous years to start as the basis which allowed for multi-year customization and back testing.

Guess I'm not using Turbotax anymore.
