Calif FTB wants me to file 2006

[ilaureeclyd2018]

CA FTB revenue agent says to make them up sine IRS Don’t keep returns that old.

neither Turbotax nor the IRS keeps returns that old.   I don't think the forms are available online or by phone so you'll have to request them by mail

do your best.  I would also attach a statement that says "actual tax documents from 2006 are not available. i used my best effort to estimate the amounts reported"

are you sure it's actually from CA FTB, I mean almost 15 years is a long time for them to wait?

There is no Statute of Limitations with California FTB if you failed to file a 2006 return in the first place.
