The change in your tax situation is partially the result of the Tax Cuts and Jobs Act of 2017. For 2018 your standard deduction is $24,000 which exceeds the potential Schedule A itemized deductions you've indicated which total only $22,060, so you get the standard deduction for 2018. However, the main difference appears to be that you had $55,000 of itemized deductions in 2017, far more than the $22,060 of potential itemized deductions for 2018. The difference in potential itemized deductions appears to be the main reason that you have $37,000 more taxable income for 2018.
