Don't think you'll encounter double license problems because you don't have two main business locations.  I use my home laptop for WFH days and then transfer the data file via my Dropbox account. 

I have efiled from home too without any 'issues' from ProSeries but it is better to do that from your main location, keep Homebase from deceiving you!  And if it's a lengthy tax prep which you might be switching back and forth re locations, very important to keep track of the latest version...avoid overwriting the data file 😧!
