I've used the Delaware website for years, anyone that is required to file a return for the state can either submit their return(s) via tax software or use each states website. All states have them, I've previously used VA and CA.
At the end of entering your data the website determines what documents you need to attach. At this point it's just saying the return from the other state (MD).
This year I had to submit a Schedule A, didn't last year, so I filled out the Delaware Schedule A and uploaded, every year states make changes, that's what government does...
I don't read the instructions as that's supposed to be the benefit of using tax software, just answer the questions...
In any event it does have the same calculation TurboTax used, the website obviously isn't matching their instructions, so I'll see what happens when I file...
