You'll need to create a Return chart yourself for anything other than Solar and Lunar Returns.....You can do this at www.astro.com
First, go to the "Ephemeris for 6000 Years" and choose the year of the Return you want to study. Find the day where the position of say, Venus, is almost exact to your natal Venus. Go to astro.com, Extended Chart Selection, and set up a new Event (you have a choice of Male/Female/Event). Guess at a "birth time" and display the chart. If Venus is not exact to the degree and minute, go back and edit the birthtime as many times as you need to until get exact degree/minute so you'll have an accurate VR Ascendant.
