I see on your screenshot two possible values with high skewness. May you tell more about the reason why you decided to have this as a regression problem? And what regression metric do you assume for this project?
You can change the data type of the variable with Var Type Transform in the menu on the Data tab then re-select it. Also, I believe you mentioned previously that you want to bypass the limit on needing at least 20 minority class examples, so upsampling (essentially raw data + simulation or basic resampling) would be a good approach.
