Google Merchant Center Shipping & Tax

Hi,

I submitted my feed and all items are disapproved in the Google Merchant Center. According to Diagnostics, this is due to Missing value [shipping] and Missing value [tax].

It is not clear what to enter for “Shipping Service Name” (just Standard Shipping?).

Do we select Carriers or Partners?

What do we enter for “Add ship from address” ? A Spreadshirt address? If so, which one?

Do we set all locations as needing to charge sales tax? Or …?

The steps outlined in the blog didn’t seem to go into detail to address these issues. I could only upload one screenshot because I’m new.

Thanks for your help!
