Hi, Phil.
I'm not familiar with the Sprint spinoff, but the rules for spinoffs generally are well-known - and discussed here often.
The total basis (normally the cost) of your Sprint investment hasn't changed, but now it is split between your old Sprint share and your new Embarq shares. The tax code says to allocate the original basis among the old and new shares based on the fair market values of the shares immediately after the spinoff.
You didn't say which Quicken version you are using. Older Quickens had "Easy Actions"; the new versions use a drop-down list when we click Enter Transactions. Use the one labeled "Corporate Securities Spin-Off". The only tricky part is Quicken's terminology. The form asks for "Cost" of the old and new shares. It should ask for the FMV immediately after the spinoff. Once Quicken knows these values, it can properly allocate the original basis among the old and new shares.
As a test, after entering the spinoff transaction, make sure that your total basis of the old and new shares equals your original basis in Sprint. This doesn't prove that it's right - because you could get that answer by allocating zero to Embarq and leaving Sprint unchanged - but if the total is not right, then something is wrong.
I don't download transactions. The few times I've tried, I've spent more time tweaking the results to suit me than I've saved by downloading. So I can't speak to that aspect of your situation.
