Why is the Total Tax amount calculated for Line 11a by TT 2018 Premier different than the value calculated by hand using IRS 2018 Tax Computation Worksheet—Line 11a.
The value for Total Tax (line 112 of Form 1040) TurboTax 2018 is entered without any backup information. It says to "see instructions."
Using the instructions in the IRA Document, 2018 Instruction 1040 TAX AND EARNED INCOME CREDIT TABLE, page15 yields a different amount than TurboTax.
Which is correct? It would be very helpful if the software showed how the Total Tax value is calculated. If there is an error, please correct it and notify user of the error.
I am not showing the detailed calculations for privacy reasons; however I can say that the IRS value was more than $2000 higher than TurboTax's value.
