I like most of it.

"Compared to preparing your tax return by yourself,"

Compared with trying to do this manually...

You don't "save taxes." You want to accurately report and pay taxes only on what you are required to pay taxes against, so you want to reduce errors, and take full advantage of all provisions that apply to you, and in general, avoid overpaying, which is not the same as saving. Using software helps you avoid costly mistakes.

I really like this part: "However, tax practitioners have noticed that TurboTax’s question-based system and artificial intelligence may not spot all relevant tax federal and California tax requirements and tax-saving opportunities - whether this year or the longer term. The more complicated your tax picture, the more chances for error with TurboTax."

Especially business people need to know that the tax provisions applicable to them are not well managed in TT. Since they already need to know about their business to stay in business, they should not also need to learn all the tax code required to know if this is being handled well in TT and that's why they, as a professional, would turn to (someone like) you, as a professional. We can't all know everything about everything.

Then, point out how the "supply chain" in tax law changes affected you as a professional, while waiting on Congress and the President to pass retroactive provisions, the software delay in implementing the updates, and the people that filed early anyway. File early, file often!
