Can I get part of next years tax return this year

What do you mean next years?  You mean your 2020 return you file in 2021?  No.

Reduce your number of exemptions for 2020 and you will receive more money in each paycheck this year. But be careful not to overstate you exemptions because you can end up owing money when you do 2020 tax return.
