Please quote where he said to not vote.
“If we don’t solve the Presidential Election Fraud of 2020 (which we have thoroughly and conclusively documented), Republicans will not be voting in ’22 and ’24,” Trump said in a statement released Wednesday. “It is the single most important thing for Republicans to do.”
Hope that answers your question. And please I don't want to get into a "who shot John" argument here.
If he didn't say it then I expect he might take issue, in court, with National Review, a specious publication at best.
Now if you have insight into the man's mind and wish to explain what he meant when he said it, please go ahead. I'll just accept your interpretation and it will end this exchange.
