I am working on a time series and trying to fit ARIMA to predict future values.However, I am facing trouble with finding out whether the data is stationary or not.

I believe you know how to check whether the data is stationary or not by looking at the ACF & PACF plots.

To do this in Minitab, we use Stat - Time Series - Autocorrelation and Stat - Time Series - Partial Autocorrelation.

With no data given here I would suggest you to refer this document. Hope this helps !
