How do I print Estimated Tax forms without amounts printed?

I love using the pre-printed ES forms for both state and federal from TT because they already have our address, names, SS# and I like this a lot more than having to fill all that out by hand. However, we don't want to pay what TT says to pay pre-printed, as we make very different income every year and at various times of the year. I always calculate this number myself depending on how much money we've made for each quarter. Right now the first quarter due April 15th wants way too much. Is there a way in the software to get it to print everything but the amount so I can write that in? 

Alternatively, does anyone happen to know... must EST forms be always paid with a physical check with these coupons by mail or is there any way to pay through a Bill Pay service and still have it credited to us properly?
