How can I adjust the spacing around my Shop Pay Installments message?

[mbco]

I just barely updated to accept Shop Pay Installments. Now there's a big space between the price and the installments message. It's also too close to the buy now button. I'm assuming the coding is clashing with something else. If someone could help me out with this, it'd be much appreciated. Thanks!

Please add below css in assets/theme.scss.css file 

.product-form__controls-group--submit {  

             margin-top: 20px;

}

.product-form { 

           padding-top: 1rem ;

}

Thank you.

In my assets folder I only have a theme.scss.liquid file. I tried pasting it in that one and my main theme.liquid file and neither of them worked. Possibly have any other suggestions?
