Can I make a tax payment for 2017 prior to filing return and if so, what form and will it save me penalty. Is there a date were if paid I will not be penalized?

I underpaid 2017 federal taxes by $6,000. I can't file until I receive K-1. Can I make a tax payment of $6,000 for 2017 prior to filing return and if so, what form and will it save me penalty. Is there a date were if paid I will not be penalized?
