Yes it all depends on your tax liability. You have to complete the AMT portion even though you may not filing. My remaining portion was 200 so that was the max I could take
Per irs instructions
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.
Line 19
If you can’t use part of the personal portion of the credit because of the tax liability limit, the unused credit is lost. The unused personal portion of the credit can’t be carried back or forward to other tax years.
I have not tried to file since the error. I am on desktop
