You can pray for grace to accept with serenity the things that cannot be changed.  This glitch apparently has been in the software for several years at least, and they aren't going to fix it just for you.  But are you sure you want to file electronically?  You would still have to mail the 8283 signed by the appraiser and the donee. Maybe even the appraisal.  I wouldn't want the meat and potatoes of a return going one place and the gravy going to another.  Especially, when IRS hates conservation easements, because most of them are manufactured by syndicates rife with fraud.
