I’m not quite sure about indexing the https pages over http, but I can say the following will really help:
Make certain you’re forwarding http to https for ALL of your indexed content
Make certain that you are not serving any “mixed content” on ANY of your pages (i.e. no content from http sources) (https://www.missingpadlock.com)
rel="canonical" tag to every unique page to indicate its proper address and ensure your are only serving from that address in terms of using https protocol and the correct (sub)domain (https://moz.com/learn/seo/canonicalization)
sitemap.xml file to the root of your site containing the canonical addresses of the primary pages you want indexed (https://www.sitemaps.org)
robots.txt file to the root of your site containing at least a sitemap line (e.g.
Sitemap: https://spokaneplanner.com/sitemap.xml) (https://www.robotstxt.org)
https://spokaneplanner.com/sitemap.xml -> https://spokaneplanner.com/sitemap_index.xml :
