Get your taxes done using TurboTax

Estimated Tax Payments (Line 65) for my Federal and State Tax Filings were Adjusted/Corrected, slashed from $3000 to $0.

I own a small consulting LLC for which I paid estimated taxes throughout 2015 as well as myself via a W2.

I asked this forum "Where do I enter tax deposits previously paid from Form 941?" to which I was guided: "Estimated Taxes you paid for the year are entered under Deductions & Credits >> Estimated Taxes >> Federal Estimated Taxes, by quarter."

1) I summed each quarter's Form 941 payment to Federal EFTPS, Is that the appropriate content for Estimated Taxes?

2) Should I appeal the IRS decision directly or is that something for a professional (CPA, Tax Lawyer, etc)?
