Always paid quarterly, but with new tax laws got all of it back, so if my income will be same in 2019 do I not pay quarterly in 2019.

No, you do not need to pay quarterly in 2019 if you received all of your estimated payments back for 2018 and your income will be the same.  

The Tax Cuts and Jobs Act (TCJA) that Congress signed into law on December 22, 2017 is effective for Tax Years 2018 through 2025.
