Odoo 12.0+e (Enterprise Edition) - Ubuntu

I am trying to import Order Lines and have them connected to Quotations that I have already imported.

First error I get is:

Missing required value for the field 'Customer' (partner_id) at row 2

So I try to connect the Customer IDs via 'Customer / External ID' which yields:

Unknown error during import: <class 'odoo.exceptions.MissingError'>: ('Record does not exist or has been deleted.', None) at row 2
Resolve other errors first

Now I check on the IDs and as far as I can tell, they ARE there.  The Customer fields are linked properly on all Quotations.

I've tried to import them like this

__import__.zcrm_1441198000000217205

and this

zcrm_1441198000000217205

What am I missing?
