Hello, dwedeman.
I'll share about the Schedule E supportability for QuickBooks Self-Employed. I'll also point the way and ensure you'll be able to convert your transactions under Schedule E.
QuickBooks Self-Employed only supports Schedule C categories. However, we do have Schedule E categories in TurboTax.
Since you need to report your real estate income under Schedule E, you'll want to contact TurboTax support. One of their agents will set you up and ensures that you'll be able to convert those Schedule C categories to Schedule E.
You can find their contact information here: https://support.turbotax.intuit.com/contact/.
TurboTax has an article about Schedule E. Check it out if you need some references: https://turbotax.intuit.com/tax-tips/rental-property/what-is-a-schedule-e-irs-form/L8h73YEqU.
