Thanks again for the reply.
I tried a few things but Turbotax online simply will not let me change the amount of the refund I'm applying to this year's taxes.
I have a hunch this has something to do with IRS rules. I'm guessing that the IRS lets you amend the data, but doesn't want you messing with the refund information. Probably it's an anti-fraud measure, so that scammers don't file amended returns asking for a $1 million refund or whatnot.
I assume the IRS is going to see that I'm asking to apply an amount next year's taxes which is larger than my refund and that surely will be disallowed. I'll bet this is a common mistake and they'll just catch it and correct it.
That's my guess anyway. For the moment, I'll just wait for the IRS and CA to send me a letter, as they usually do...
I realize this is a niche problem. Thanks again for your help.
PD
