Great question @KHA1 ,
Unfortunately it is difficult for me to know without reviewing your previous years tax returns. There can be reasons that you received significant refunds such as the ages of your children, tax credits, investment losses, and others. These can change year to year and the result can catch taxpayers by surprise.
Without the detailed information available to me, my recommendation is to make the estimated payments and then claim a nice refund at tax time!
Thank you!
