you can try keeping "price" column in the dataset in the first Box,
Enter Data manually: price,column2,col3,....col10
Select Columns in Dataset: price,column2,col3,....col9 (choose which columns to import, omit col10 for example) Though the learning path says to remove price column, try keeping it in.
And you may be interested in Edit Metadata asset box. It allows your model to import the columns and associate the features with the predicted price. So instead of just seeing a predicted price, you can output, what you fed the model. Overall, did you get it to work by starting over? That learning Path worked for me when I followed all steps. maybe these extra ideas will help.
