How to input a non-estimated pre-filing payment? Paid online as a 1040 payment (not 1040ES) for 2018 in March. Line 66? Can't edit line 74?

I don't want the IRS to be confused by a mismatch if I put it on line 66 as an estimated tax payment, because it wasn't submitted with a 1040ES.  I think technically it should be on line 74, but I can't figure out how to edit line 74.

It is still considered an estimated payment, even if there is no 1040-ES.

Here are some things to know for taxpayers who make estimated payments :

• Taxpayers can pay their taxes throughout the year anytime. They must select the tax year and tax type or form when paying electronically.
• Filers paying by check should make it out to the “United States Treasury” and indicate the tax year and type of taxes they are paying.
• Taxpayers in presidentially-declared disaster areas may have more time to make these payments without penalty.
• For easy and secure ways to make estimated tax payments, use is IRS Direct Pay or the Electronic Federal Tax Payment System. IRS.gov/payments has information on all payment options.
• Taxpayers can find more information about tax withholding and estimated tax at the Pay As You Go page IRS.gov.
• Publication 505, Tax Withholding and Estimated Tax, is another resource for taxpayers. Publication 505 has worksheets and examples, which can help taxpayers determine whether they should pay estimated tax
