Amending 2018 return to change deduction method

Hi,

 

I drive for Uber and in the 2018 tax return that was filed last year ( in 2019), the itemized deduction method was used instead of the standard deduction method, in error. The standard deduction gives more $ deductions than the itemized method. Considering this, can the return be revised/amended now and if so, will I get additional refund from the IRS and State (Massachusetts)?

 

P.S. For the previous years - 2016/2017 standard deduction method was used.
