Tax Year Prior to 2020: How can I pay 1040NR tax on online?

I have due to pay 2019 income tax.

 

I tried to pay in IRS site, but I only can find direct pay for 1040 filer.

 

Could I pay on online?

 

If yes, could you link the address please?

 

If no, how can I pay it? only mailing check? Can I pay it on EFTPS?

 

Appreciate your helps
