It was supported before, but wasn't available until Feb 22, 2021.   I was hoping it would be soon.

I dont even see an option to install it, wasnt available to install in 2020 either

LA doesn't distinguish between Corp or S-Corp, so with that said...I guess my question should be "when will the 1120 LA software be available?  I have the product selected, but inside the tax return for States..LA is not an option.

That one IS in the release dates  https://myproconnect.intuit.com/releasedates

Looks like 3/4

Since when, it has always been available and I have been using your program a long time.

This is correct. Louisiana uses the C-Corp return. It originally was going to be available today, then it was pushed back to March 4th. I figure it will be pushed back again.

I've spoke with several other CPA firms, all have the Louisiana Corp available in their software. Just like the 8915-F.

Maybe by March 31st......

I checked and installed the 2021 LA 1120 state return module and the LA now shows up on my 1120S returns. There is no tick box to install LA on 1120S but it still works.
