Thanks very much again Tom.
I now understand what you suggested earlier "Form W-4 and estimate taxes" as this is the only way to come up with a best guess estimate of my 2018 income to pay taxes using the best guess tax rate and not just 12%.
I went through the TT questions and got the 2018 estimated tax vouchers with 4 equal amount to pay.
Once again, I really appreciate your help and the info.
