@dGKodes - It appears that TurboTax is following the IRS 8911 that says to use line 33 of the 6251 (tentative AMT) on line 17 of the 8911 (and not the actual AMT) to calculate the allowable part of the credit.
From the IRS 8911 instructions for line 17: <a rel="nofollow" target="_blank" href="

Line 17
"Although you may not owe alternative minimum tax (AMT), you must still figure the tentative minimum tax (TMT) to figure your credit. Complete and attach the applicable AMT form or schedule and enter the TMT on line 17."
