I paid Alternative minimum tax in 2015 of 9,395; 2016 of 8,367 and 2017 of 10,800. The 2018 return used the 10,800 prior year AMT as a credit for 2018 regular tax. Do I have available the 2015 and 2016 AMT tax as a credit carryforward to 2019 regular tax?'
Most all the AMT tax is result of disallowance of itemized deductions available for regular tax computations ( taxes from Schedule A)
Although used up the 2017 carryforward to 2018, this only represents the 2017 AMT tax, not previous years 2015-2016??
