Self assessment tax or advance tax for ay 19-20

can i pay it as self assessment tax instead of advance tax?

Thank you!

Does it make any difference if I pay Self assessment tax? Is it allowed in e pay tax website If i proceed with Self assessment tax?

As a Salaried employee, Usually it's company's responsibility to deduct TDS, which it failed to deduct in this case, & there is no requirement of advance tax if all the TDS deductions were made. Hence I am paying only the balance tax and not a advance tax

But the portal did not allow me to pay advance tax and instead i paid self-assessment before 1.4.2019

My bad it was advance tax
