Can someone help with the quarterly estimated side of this?
I need to make a quarterly payment for 2006 with my return. Also the next quarterterly payment is coming up in June.

Thinking of just paying them now during the bonus period with the SPG Amex.

Do I need to be able to specify which quarterly payment I'm making?
Should I just do it in one transaction or should I do to separate transactions?

Thanks,

Scho
