For this discussion, ignore the effect of income tax liability (LLC or S corp) and estimated tax. 

The issue is illustrated below with 100S Line Numbers.  Same result for 565 and 568.

If Form 3804 shows an amount, it flows to 100S Line 29.  Let's say the amount = 10K

My logic:

1. If the payment has YET to be made, Line 35 should be zero, Line 40 Tax due should be 10K.  Voucher 3893 (PTE) should be printed. Voucher 3893(ES) also printed.

2.  If the payment has been made, line 35 should be $10K, Line 40 Tax Due should be zero.  NO voucher 3893 (PTE) for 3/15.  Voucher 3893 (ES) for 6/15 printed.

Lacerte is the opposite.  If I enter $10K on Line 35, the balance is zero (correct), but voucher 3893 (PTE)  and 3893 (ES) are BOTH printed with instructions.

If  I enter zero on Line 35, the balance is $10K.  Voucher 3893 (PTE) and instructions are NOT printed.  ONLY 3893 (ES) and instructions are printed.

I tried to explain to Lacerte and Kenneth kept telling me I was wrong.  Was I??  Am I losing it?

I believe CCH does it "My Way"...
