Welcome to roll20 Michael. You really cannot "import" a sheet into roll20. There are a handful of official sheet's written and maintained by roll20 but by and large most sheets are created and maintained by the roll20 community using html/css/js. If your specific system/sheet is not listed(create a game and check the character sheet template list. I did not see Outbreak Undead listed.) there are at least a few options to consider; manually create one using html/css/js (requires a Pro account and at least some basic skills): Building Character Sheets use a sheet located outside of roll20 (maybe a local copy, google docs, or whatever.) make a request to the community for a sheet to be made (there's always a long list of requests with few sheet authors.): Character Sheets & Compendium don't use a sheet at all and instead use a character journal entry (Bio) along with manually creating Attributes & Abilities and macros.
