E-filing is closed right now until the IRS begins to accept e-files again in January, when they open up for e-filing 2020 returns. So you can wait to e-file it in mid-to late January or you can mail it now.
Either way--be aware that it is taking the IRS about six months to process amended returns, so do not expect quick results from amending.
