Which Ancestry test did you take? If it's the $99 one the next paragraph applies. Ancestry does offer the Paternal and Maternal Lineage tests, but they haven't pushed them in a while.
For the AncestryDNA test ($99 these days, was bit higher a while back) - All you need is your Ancestry user name. If you uploaded to GEDmatch, you can add your GEDmatch ID, and if you have any information you would like to add. Some people add their ethnic/ancestry percentages or other information. This test doesn't give haplogroup, number of markers, etc. and it is the first AncestryDNA test on the drop down menu.
