Should I send quarterly estimated taxes (2018 Form 1040 ES Vouchers) now (Feb. 2019) if I neglected to send them in during 2018 and will it reduce any "late" penalty?

No, it is too late to send them now. The idea behind quarterly payments is that IRS has a pay-as-you-go system. The payments are made throughout the year, like withholding on a W-2.

Any payment made now is a normal payment made with your tax return for a balance due.
