I am attempting to use USLCI to get data for an LCA project, but after creating a product system and calculating was not able to access any impact method options in the drop down.

TRACI works with all my other databases, and I have the most recent version of USLCI downloaded. What am I missing?

Can you confirm, are you using the USLCI from the openLCA Nexus or are you using USLCI from the Federal LCA Commons (lcacommons.gov). If the latter, you need to use compliant LCIA methods and not those from the nexus. Those can be found as their own repository on lcacommons.gov or here: https://www.lcacommons.gov/lcia-methods-without-flows
