I have both the tstat and the degrees of freedom, is there a quick way to find the P value of a two tailed hypothesis at a significance of 0.05

Shouldn't p multiplied by two for a two-tailed p-value?

It should be noted that t should be positive to obtain sensible results and yes, p should be multiplied by 2 to get a two-tailed test.
To have t positive, replace it by abs(t).
