Amended Tax Return 2020 Question

My wife and I got married in 2020. I accidently filed my tax return, Married Filling Separately for 2020. I would like to do an amended tax return. My Wife has not filed her tax return yet. Can I send in an amended tax return (Married File Jointly) for both my wife and I with out her filing a tax return? Or do I need her to file her tax return Married Filing Separately and then submit an Amended Tax return (Married Filing Jointly). Any help would be greatly appreciated!
