Should I sell stock to put it into my Roth?

I have $150k in stock and 50k in Roth, but I’m currently broke af and can’t contribute to my Roth. Is is a good idea to sell stock at a gain and move it to my Roth? Thank you for the input. I’m the first in my family to ever invest in the stock market and nobody in my family knows anything about finance so just trying to figure out what to do
