After reaching a certain level of income, it just makes sense to go to a CPA/tax attorney. To me, something are just best left to the pros. Certainly, today if you are pulling in just a W2 wihin a five figure salary, turbo tax it. But given you already have to pay this much AMT and at total rate of 27%, I have to assume your income is well above the $300k mark. If you are not above $300k then you are most likely paying way too much.
At the level of income I’m assuming, the Art of Itemized Deduction becomes extremely critical. This is where a live body is needed to provide solid advice and redirect if you are too aggressive and provide hints if you are “underestimating.”
Plus the fee itself is a deductible expense!
Addendum: in regard to the not spending part. If you are an individual propriator, there are things that you spend that are 100% deductible, right off the top. Maximize those to get you down to a lower bracket, otherwise you lose it to the government.
